solved

you could use 'gate' to gate the metro to one of the counters, but you don't even need to do that, you can attach the radio-group directly to just one counter's 2nd 'set direction' inlet(0 = count forward, 1 = count backward; ...delete the 2nd counter altogether) and it'll do the trick:

also, since you mentioned you're new, just in case you find it useful for future reference: if you ever want to paste a patch to the forums, you can 'Select All' then choose 'Copy Compressed' from the 'Edit' menu, then paste here(make sure you're in patching mode, when selecting-all at first).

Hope it helps, Welcome to Max :) 🍻
